  1. Central Processing Unit CPU or Processor

  2. Central Processing Unit Components Control Unit Arithmetic & Logic Unit

  3. Central Processing Unit Control Unit Reads & Interprets Program Instructions Directs the Operation of the Processor Controls the flow of programs and data into and out of memory

  4. Central Processing Unit Arithmetic & Logic Unit Arithmetic: Addition, Subtraction, Multiplication, Division Logic: Comparisons

  5. Central Processing Unit Machine Cycle Fetch Decode Execute Store

  6. Central Processing Unit Fetch Calls an instruction into memory

  7. Central Processing Unit Decode Figures out what the instruction is trying to do

  8. Central Processing Unit Execute Does the decoded instruction Add 2+2

  9. Central Processing Unit Store Puts the answer 4 into memory for use by another instruction

  10. Central Processing Unit Clock Cycle A Crystal Oscillator on the Motherboard It paces the machine cycle

  11. Central Processing Unit Clock Cycle Measured in MHz or GHz Megahertz = 1,000,000 cycles/sec Gigahertz = 1,000,000,000 cycles/sec

  12. Central Processing Unit Clock Cycle One clock cycle is calculated by dividing 1 by the MHz or GHz Example: (800 MHz CPU) 1/800,000,000 = 0.00000000125 or 1.25 nanoseconds (nano = billionth) (1.25 billionths of a second)

  13. Central Processing Unit Clock Cycle The shorter the clock cycle the faster the processor

  14. Central Processing Unit Pipelining Executing multiple instructions at the same time

  15. Central Processing Unit Parallel Processing Multiple processors work together to complete a set of instructions CPU 01 Control CPU Answer CPU 02

  16. Central Processing Unit Dual-Core A dual-core CPU combines two independent processors and their respective caches and cache controllers onto a single silicon chip

  17. Central Processing Unit Dual-Core

  18. Central Processing Unit Dual-Core Advantages Less Power Less Space Better Performance

  19. Central Processing Unit Dual-Core Disadvantages Require Different OS Scalability more limited Lower production yields
